Domain:Binds to transcription factors via its WW domain. ,Domain:The PDZ-binding motif is essential for stimulated gene transcription. It localizes the protein into both punctate nuclear foci and plasma membrane-associated complexes. ,Function:Functions as a transcriptional coactivator. ,PTM:Phosphorylated. Phosphorylation results in the inhibition of transcriptional coactivation through YWHAZ-mediated nuclear export. ,similarity:Contains 1 WW domain. ,subcellular location:Concentrates along specific portions of the plasma membrane , and accumulates in punctate nuclear bodies. When phosphorylated , is retained in cytoplasm by YWHAZ. ,subunit:Binds to SLC9A3R2 via the PDZ motif at the plasma membrane. Binds to YWHAZ in vivo and in vitro through the phosphoserine-binding motif RSHSSP. ,tissue specificity:Highly expressed in kidney , heart , placenta and lung. ,
